As we all know, each Bluetooth product shall work according to Bluetooth specification. It is fairly big specification, and that’s why before releasing your Bluetooth product it is very important that it can talk to other Bluetooth devices. Basically, we should check if we understand specification in the same way as others. That is why UnPlugFest (UPF) is organized 3 times per year by Bluetooth SIG, so developers can test their solutions with other products to verify they work together. Codecoup understands that and encourages its customers to be there. Speaking of which, we just came back from UPF56 in Atlanta where we had two teams testing two different IoT platforms.
